TRIM AIR OFF的意思|示意

I've just revealed that my family has decided to shut the air-conditioner off, and trim our electric bill.

我才刚刚跟他说了我家人决定要关掉空调，节省电费开支。

You can record videos (at a high 720 by 480 resolution, although they don’t look any sharper) and upload them to YouTube, but you can’t trim the dead air off the ends first.

你可以录视频（分辨率为较高的720 x 480，尽管看起来不是更清晰）并上传到 YouTube，但你不能先剪辑掉头尾的停滞区域。
